Smog pump going?
Recently been hearing an occasional high pitch squeal from the smog pump area. Today with the engine running it looks like there is a slight wobble at the pulley. What is the best way to test? Going to remove the belt and check for play but I dont know what is normal so any help is appreciated.

Take the serpentine belt off and see if the pulley turns by hand. Sure, you can replace it with another air pump or pulley and block off the exhaust manifold but before we toss parts, see if it is ok,.

It does turn by hand. How freely should it spin. It's not really spinning much, maybe 1/2 to 1 rotation rolling it with my fingers. I'm thinking it's shot! No play in the pulley but it's not straight either- like a bent bike wheel.

If the shift is bent, replace. What with, depends on what you want.
